Specification of Letters Patent.

Application filed ApriIS, 1913.

Patented July 14, 1914. Serial No. 758,740.

To all whom it may concern Be it known that I, PnnssLEY A. C. Moonn, a citizen of the United States, residing at the city of Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Current-Motors, of which the following is a specification.

My invention relates to a novel means for applying the force of a current runningcontinuously in one direction for the propulsion of machinery or other like use and the object thereof is to provide cheap, simple and eflicient means for that purpose.

Another object is to provide a device consisting of one or more units, each complete in itself, which may be operated independently of each other, and which may be connected and disconnected when desired to produce a greater or less amount of power as required, and which can'be adjusted to suit the varying height of the water in the stream.

I accomplish these objects by the device described herein and illustrated in the accompanying drawingsforming a part here of in which:

Figure 1 is a side elevation of one unit of my device in its operative position in the bed of the stream. Fig. 2 1s a top plan of the parts shown in Fig. 1 with parts broken away for clearness of illustration. Fig. 3 is a section on the line 33 of Fig. 1. Fig.

4 is a side elevation of the raising and lowering mechanism. Figs. 5 and 6 are respectively an end and a front elevation of one of the power buckets or paddles.

While I have shown my device as applied to continuous running current as in a river or other like stream and will describe it as so applied it will be understood that it may by slight modifications be adapted to utilize the forward and return flow of Waves.

It will also be understood that it may be mounted upon a fioat or like structure if desired, and anchored by suitable anchoring means at the place where power is required and may be moved from place to place as desired.

Various arrangements may be made of my device.

In the present case I have shown one unit only it being understood that the units are duplicates.

In the drawings I have shown a stationary supporting frame A which is preferextending side bars j which are parallel with the poles 10 of the supporting frame and are connected at the top and bottom by cross bars 15 and 16 the ably composed of piles or poles 10 of which there are four on each side and are preferably driven into thebed of the stream and are connected at the top by cross beams 11 running longitudinally thereof and an adjustable chain frame B disposed vertically adjustable within the stationary frame A.

Power frame B is composed of'upwardly 12 and end bars 13 whole forming a rectangular frame. Side bars 12 have secured thereto at the top and bottom of the sides thereof bearings 17 and 18. The upper bearings 17 have mounted therein shafts 19 on the ends of which are mounted sprocket wheels 20 and the lower bearings 18 have mounted therein stub shafts 21 on which are revolubly mounted sprocket wheels 22. On the outer side of the shorter end of frame B and secured to the end bars 13 are bearings 23 in which is revolubly mounted a shaft 24 which shaft has secured upon the ends thereof sprocket wheels 25 and 26. Upon the outer side of the end of frame A preferably the downstream end and secured to the poles 10 are bearings 27 and 28 which have mounted therein a power shaft 29. Sprocket wheels 30 and 31 are secured upon this shaft next adjacent the inner side of the bearings and project between poles 10. A suitable clutch and governor is mounted upon one end of shaft 29 from which power is transmitted by a belt 32 or other means to its place of use.

An endless sprocket chain 33 connects sprocket wheels 30 and 25 and a similar chain connects sprocket wheels 31 and 26 and are supported intermediate said sprocket wheels by idler sprocket wheels 20 and 22. These chains have pivotally secured to the inner or adjacent sides thereof, at suitable distances apart power buckets or paddles 35. Extending outwardly from each end of these buckets adj acent the pivots and a little below the same and preferably integral therewith are ears or lugs 38 and 39 which are adapted to bear against the inner side of the chains and prevent the buckets being tipped over by the flow of water. Counter weights 40 are provided at suitable distances apart and are secured upon one end of a rope or cable 41 which cable passes over a sheave wheel 42 mounted upon the top of frame A and then extends downwardly and is connected to the.

top of frame B. Securely mounted upon the top of frame A at about the center thereof are bearings 48 and 44 in which is mounted an adjusting shaft 44 Shaft 44 has rigidly secured thereon adjacent the inner sides of the bearings miter gears 45 and 46 which are in engagement with miter gears 47 and 48. Gears 47 and 48 are revolubly mounted in bearings 49 and 50 secured upon the inner sides of cross beams 11 as best shown in Fig. 4. The upper ends of adjusting screws 51 and 52 are rigidly secured within mitergears 47 and 48and extend reach the hand downwardly therefrom and thelower ends are received in threaded engagement within threaded bearings 53 and 54 secured upon I the sides of frame B. A hand wheel 55 is mounted upon one end of shaft 45 and provides means to raise and lower frame B. A

suitable platformv or staging (not shown) will be provided to enable the operator to wheel when desired.

In operation the device will be placed with the buckets opening upstream. The force of the current will then fill the buckets and carry the same downwardly with it thus I causing the chain to rotate the sprockets and shaft 29 from which shaft power will be transmitted by a belt or other meansto the place of use.

Having described my invention what I claim is:

1. A current motor comprising a stationary frame; a chain frame vertlcally movable wlthin said stationary frame; a power shaft revolubly mounted in one end of the chain frame; another shaft revolubly mounted on one end of the stationary frame; sprocket wheels on each of said shafts; sprocket chains mounted on said sprocket wheels; power buckets on said chains; means to raise and lower said chain frame and means to utilize the power from the shafts.

2. A current motor comprising an outer supporting frame; a chain frame within said supporting frame; a shaft on the chain frame; another shaft mounted on the sup porting frame; sprocket wheels on said shafts; chains on said sprockets; power buckets on said chains; and means 'to utilize the power from the shafts.

3. A current motor comprising a stationary frame; a chain frame vertically movable within said stationaryframe; a shaft mounted on the stationary frame; another shaft mounted on the chain frame; sprocket wheels mounted on said shafts;

sprocket wheels; power buckets on said chains; means to raise and frame within the stationary frame; and means to utilize the power of the shafts.

4.; A current motor comprising a stationary frame; a chain frame mounted vertically movable within said stationary frame; a shaft revolubly mounted on one end of the stationary frame, said V mechanism mounted upon one end thereof,

and a pair of sprocket'wheels; a shaft on the opposite end of the chain frame; a pair of sprocket wheels on said sprocket chains passing over anddconnecting said shafts and sprockets; power buckets mounted between said chains and pivotally lower the chainshaft ;-a'-pair of sprocket 1 chains passmg over and connecting said shaft having aclutch r' secured thereto; idler sprockets mounted] to support said chains intermediate the main sprockets; means to raise and lowersaid chain frame to suit the varying heightof the water.

In witness that I claim the foregoing I have hereunto subscribed my name this 24 dayof March, 1913. V
